Abstract (en)

[origin: EP2369155A2] A gas turbine engine nose cone assembly (40) comprises a tapering spinner (42). The tapering spinner (42) has a point (44) at a first end (46) and a circular base (48) at a second end (50). The tapering spinner (42) comprises a carbon fibre containing composite material layer (70), an electrically insulating layer (74) arranged on an inner surface (72) of the carbon fibre containing composite material layer (70), an electrically conducting layer (78) arranged on an inner surface (76) of the electrically insulating layer (74) and an electrically conducting member (80) extends through the first end of the tapering spinner (42) and is connected to the electrically conducting layer (78). This arrangement provides lightning protection for the gas turbine engine nose cone assembly (40).
